Under the law a Principal Military Deputy serves with the Assistant Secretary of the Air Force for Acquisition. The Principal Military Deputy is required to be an active duty officer with a background in acquisition and program management.

Of the five Assistant Secretary positions established by law, only the Assistant Secretary for Acquisition is required to have a Principal Military Deputy.[1]
Before Andrew Hunter, Darlene Costello served as acting Assistant Secretary for the second time. During the Obama and Trump administrations, Costello served as acting Assistant Secretary, from February 2016 to February 2018.[2] In 2018, Will Roper was confirmed to the role, serving from February 2018 to January 2021.[3] Despite Roper's requests to the Biden transition to be retained in the position in the new administration, his efforts went unheeded, and he resigned on January 20 as is custom.[4] Upon his departure, Darlene Costello again became acting Assistant Secretary until a new Secretary is appointed. With 3 years in the role as of January 2022, Costello's service as SAF/AQ, spanning three presidencies and four Secretaries of the Air Force, ranks among the longest in the history of the position, despite never being confirmed by the Senate.

This move established the Defense Acquisition Executive, the Service Acquisition Executives for each military department, Program Executive Officers who manage execution for a portfolio of programs.
